B1F Integration Framework error on event handling

Hello all, I have a problem with B1F. I am trying to handle an event from SAP B1. I created a scenario that will be triggered by a change inside B1. The problem is I can see the event in b1f but it does not trigger the scenario.

When I tried to executed -as an admin- "run" the event handling service, it throws an error "could not find or load main class com.sap.b1i.eventsender.eventsenderapplication"
